For nearly three decades, astronomers have interpreted the faint luminosity of certain distant explosive stars as a sign of ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

Scientists have long held that the universe is expanding at an ever-increasing rate, driven by a mysterious but measurable ...

Before atomic elements came together, less than a second after the Big Bang, if particles condensed into halos of matter, ...

A team of physicists have proposed a new cosmological model – dubbed the "black hole universe" – that suggests that our universe did not begin at the Big Bang. For a long time the universe was assumed ...

Astrophysicists at the University of Chicago have developed physics-based models suggesting that dark energy could be changing over time. Dark energy, the mysterious force causing the universe to ...

A new study suggests that during a potential phase of primordial matter domination, particle interactions may have led to the formation of the universe’s first compact cosmic objects. Less than a ...

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously ...
